Make fake client actions use fully qualified resource
The output of a versioned clientset is version object. The fake client used to assume only internal objects will be returned. This PR removes this assumption by making fake actions initialized with a fully qualified resource instead of a resource string.
We have to regenerate fake clients in release_1_2 clientset to let it compile. For the test fakes, we are breaking the backwards compatibility promise.
Part of #24155.
